黑龙港区旱地不同水文年种植方式的灰色决策初探

A Preliminary Report on the Grey Decision Approach for the Planting Ways in Dry Land of Heilonggang Area in Different Hydrological Years

应用灰色系统理论和多目标灰色决策的方法,依据多年调查和研究结果,综合分析了黑龙港区旱地不同水文年了种种植方式的产量、产值、降水经济效益和降水利用效率四个目标的实际效果,提出了在不同投入水平条件下适合不同水文年的种植方式,为港区旱地科学种植提供了依据。

According to the results of investigation in many years, the prectical effects of seven planting ways in yield, output value, precipitation economic bcnifit and precipitation application efficiency in the dry land of 01 Heilonggang area and in different hydrological years were analysed using methods of the grey theory and the multiple-objective grey decision.The planting ways suirble to various hydrological years at various input levels were described which may provide basis for scientific planting in Heilonggang area.
